INKING PAD.

. Application filed .Tune 14, 1922.

To all w from t may] concern Be it known that ARTHUR B. CARnoLL, a citizen of the United States, residing at Baltimore, in the State of Maryland, has invented certain new and useful improvements in Inlring Pads, of which the following is a specification.

This invention relates to improvements in inlring pads and has reference to that class of pads which are to be more or less saturated with inlr whereby hand stamps may readily be inked.

One object of the invention is to provide an improved construction of pad which will readily receive and retain the ink; whose inking surface will remain flat and free of waves, and the fabric covering of which will be held in a taut condition and prevented from wrinkling. p

Another object of the invention is to provide anV improved base structure for carrys ing the pad which will not warp; which is so formed as to provide means for holding the fabric covering in a stretched condition without separate fastenings and which is so shaped that the pads may be readily stacked one upon another with the pad of one fitting up into the base-structure of the other.

With these, and other objects in view, the invention is illustrated in the accompanying` drawing, wherein,-

4ig. 1. shows one of the improved pads enclosed in its retaining case,-the latter being broken away at one corner to show the exterior construction of the pad itself.

Fig. 2. illustrates a cross-sectional detail through the case and pad.

Fig. 3. shows an enlarged vertical section through a portion of the base structure and pad with the edge of the fabric covering in position and ready for compressing and clamping, and

Fig. 4f. illustrates a similar view with the parts clamped and completed.

Referring to the drawing the numeral 5, designates a metal base structure having at each side a down-turned wall 6,--the walls at each side or end being separate and independent from those at another side or end in that a vertical slit 7 is made in the metal between the wall 6 at one side or end and the wall at an adjacent end or side. In other words, if the base is of rectangular shape Ithe vertical slits 7 are provided at the Serial No. 568,128.

corners to separate one right-angle side from another.

Each wall 6 carries an Lip-turned flange the free-edge 9 of which points upwardly and before the pad structure is secured in place these uo-turned flanges S will spread or incline outwardly whereby to form a V- shaped channel 10 around the several sides of the base structure as shown in Fig. 8 of the drawing.

lll-ach flange 8 of the base structure is provided with a series of tangs 11 for a purpose that will presently be explained.

llt will be noted that the walls 6, by depending froin the base 5, sustain the latter in an elevated position and thereby form a hollow or cavity 12 beneath the base. It will furtherbe seen that the walls 5 slightly Hare they extend down from the base so that the cavity 12 is slightly larger at the eXtreme bottom than directly beneath the base plate 5. The advantage of this shape of cavity will also presently be explained.

The pad itself is preferably formed by first providing a lower layer of felt 13, or equivalent material, which will lie directly on top of the base-plate 5, then a layer of blotting-paper 14, on top of the lower layer of felt, and another layer of felt 15 is laid on top of the blottingpaper.

It is to be understood that, while I have specified certain materials in the pad structure, the invention does not reside in those materials and any other suitable materials may be used.

lt is customary and desirable to provide a covering fabric 16 over the several layers of padding and to draw this fabric taut so as to provide a smooth inlring surface against which the hand stamp may be impressed when inlring it.

According to my invention l stretch the fabric 16over the padding and extend its sides and ends 17 down into the ll-shaped channel 10 of the base-structure. rlhese sides and ends of the fabric have their edges 18 turned upwardly so as to form a double-ply of material in the channels 10, as clearly shown in Fig. 3 of the drawing.

While it is immaterial to the present invention as to how the fabric 16 is stretched l may state that I hold the pad in a compressed eondition while the ends 17 of the fabric are drawn down into the channel 10 and while in the compressed condition l bend the Hanges 8 back against the ends 17-18 and clamp the latter against the Wall 6 and then I force the tangs 1l inwardly against the double-ply portion and securely lock the saine in place. The pad is then relieved of its compression and the fabric covering is left in a stretched or taut condition.

The pads may then be saturated With ink before and then stacked one upon another until they are placed in metal containers.

In stacking the pads one upcn another, it Will be seen that the pad portion of one Will projectup into the cavity l2 in the base structure of the pad above it so that, vnot yonly Will the several 'pads be covered and 4protected from dust or dirt, but they Will interlock or nest so that large numbers may be placed in one stack. l g y At any convenient time afterthe 'pads are made they may be placed in suitable containers 19 Whose Walls may be crimped in- Wardly as at 20, to hold the pads in place therein. These containers are usually provided with covers 21.

Havingdesci'ibed my invention, I clainn* l. In an inking-pad the combination ivith :a base-plate having down-turned Walls with upwturned flanges to forni a channel around the plate, of padding on the plate and a abric covering over the padding said covering having its edges extended down into said channel between .the Wall and flange and clamped between the two.

2. In an hiking-pad the combination with a base-plate having down-turned Walls With 11p-turned flanges said flanges being provided With tangs, of a padding on the baseplate and a fabric coveringover the padding and having its edges extended down between the Ysaid Wall and flanges and engaged by the 'tan'gs on the flanges. i

*'I'n an inking-pad the combination with a metal plate having a separate down-turned Wall at each side and each Wall beingnprovided With an up-turned ilange whereby to form achannel at each side 'of the plate each tip-'turned flange having a series of tangs formed therein, a paddingV over the plate, and a fabric covering over thepaddinggsaid covering having its edges extended down into the several channels and clamped therein by the tangs on the flanges. 4

In testimony whereof I alix my signature.
